How to change coal to gas floor heating? Comprehensive analysis of transformation steps and precautions
In recent years, with the advancement of environmental protection policies and the adjustment of energy structure, "coal to gas" has become a popular choice for many home heating renovations. Floor heating is popular for its comfort and energy saving, but how to change traditional coal-fired heating to gas-fired floor heating? This article combines the hot topics on the Internet in the past 10 days to provide you with structured data and detailed guidance.
1. Core steps of coal-to-gas floor heating transformation
| steps | Specific content | Things to note |
|---|---|---|
| 1. Evaluate legacy systems | Check whether pipes and radiators are reusable, and measure the insulation performance of the house | Old pipes need to be replaced to avoid the risk of later leakage |
| 2. Select gas equipment | Gas wall-hung boiler (power needs to match the house area), water distributor, temperature control system | Prioritize first-class energy efficiency products to reduce long-term use costs |
| 3. Laying floor heating pipes | PEX or PERT pipes, spacing 15-20cm, zigzag layout | Avoid large furniture to ensure even heat dissipation |
| 4. System debugging | Pressure test (0.6MPa pressure holding for 24 hours), water temperature adjustment | It is necessary to heat up slowly during the first operation to prevent the floor from cracking. |
2. Renovation costs and subsidy policies (latest data in 2023)
| Project | Cost range | Subsidy policy |
|---|---|---|
| Gas wall-hung boiler | 5,000-15,000 yuan | Subsidy 30%-50% in some areas (such as Hebei and Shanxi) |
| Floor heating pipe laying | 80-120 yuan/㎡ | There is no direct subsidy, but you can apply for an energy-saving renovation loan |
| Manual installation fee | 3000-8000 yuan | Some cities provide free survey services |
3. Answers to popular questions
Q1: Will the monthly cost increase after switching from coal to gas?
According to user measured data, the average monthly cost of coal-fired housing for a 100-square-meter house is about 600 yuan, and gas floor heating is about 800-1,000 yuan. However, gas heating is highly efficient and clean, and has a better overall cost performance.
Q2: Which houses are not suitable for floor heating?
① The floor height is less than 2.6m (floor heating accounts for 8-10cm); ② The old house has no waterproof layer; ③ The short-term rental house (renovation recovery period is long).
